when i mix my music, i always turn down all the tracks faders, so my final stereo head room will be around -20 db. then i add limiter and add something around 14 db , so my final lufs will be somewhere around -6 db (the numbers are not accurate) . but i wonder , if i dont pull down the faders too harsh , so for example my final head room would be at -10 db, then i add 4db with limiter, so my final lufs will be -6 db, is there any difference between these two methodes or they are the same? i mean is there any difference to how much i add db gain when i limiting? (i mean both of times my last lufs is -6 db. ). anybody know? thanks
Theoretically yes, they should both give the same results. The only time the limiter should be changing the sound in any significant way is when it is reducing the volume of the peaks. Simply turning the volume down and then back up should not change the sound.
You can verify that they are the same by trying the following:
- Mixdown your project to a stereo wave file for both versions
- Create a new project and import the two wave files onto two separate tracks
- Flip the polarity of one of the tracks (make sure to flip both the left and right channels)
- Play both tracks together
If they are indeed identical then they will completely cancel each other out and you won't hear anything when these two tracks play together. However, if you do hear something, then that means they are producing different reults and what you hear is what is different between the two versions.
